Thanks for all your advice.
Been to look at the van over 200 miles away it is smothered in motorway chevron stuff , doors, bonnet , back doors the lot.
He has treid a bit to remove it but damaged paintwork but I'm not to bothered about that as the van will be sign written.
But met in a car park and that put me right off, I'm still tempted as it all checks out legit.
Many Thanks
Mark
